Sweaty Betty and Lululemon are the two premium activewear brands most UK women compare before buying. They occupy almost identical price points, target the same customer, and make similar quality claims. So which is actually better? The honest answer: it depends on what you're doing and what you value.
1 | British vs Canadian — The Backstory
Sweaty Betty — London, 1998
Founded by Tamara Hill-Norton in Notting Hill. Predates the modern premium activewear category. Originally a women's yoga and running brand with a strong British aesthetic. Design team remains London-based. Acquired by Wolverine World Wide in 2021.
Lululemon — Vancouver, 1998
Founded by Chip Wilson the same year. Started as a yoga-specific brand and expanded aggressively into running, training, and lifestyle. Now global — over 680 stores worldwide. Strong cult community following, particularly in North America.
Both brands were born in 1998, both started in yoga, and both grew by building community around their product rather than just selling activewear. The parallel origin story is striking — and it means both brands have deep roots in the same category rather than being fast-fashion companies that drifted into activewear.
2 | Fabric Technology Compared
| Category | Sweaty Betty | Lululemon |
|---|---|---|
| Hero Fabric | PowerSoft — dense, matte nylon blend. Buttery feel, minimal sheen. | Luon (yoga) and Nulu — similar dense, matte construction with a cotton-like hand feel. |
| Running Fabric | Zero Gravity — lightweight four-way stretch, faster wicking than PowerSoft. | Luxtreme — sleek, sweat-wicking, supportive. Used in Align and Wunder Train. |
| Squat-Proof? | Power Legging: yes, tested under studio lighting. Engineered specifically for this. | Align Pant: widely praised as squat-proof. Luon weave is dense and opaque. |
| Waistband | Reinforced internal structure. High-rise with grip strip on most styles. | Proprietary waistband technology with internal bonding. Well-regarded for stay-put performance. |
| Recycled Materials | ECONYL regenerated nylon across multiple lines. Genuinely recycled. | Committed to recycled and responsible materials but slower adoption than Sweaty Betty. |
Honest Assessment
At fabric level, both brands are genuinely premium. Lululemon's Luon and Nulu have a slightly softer, more cotton-like feel that many women prefer for yoga. Sweaty Betty's PowerSoft has a sleeker, slightly more "athletic" feel. Neither is objectively better — it's tactile preference.
3 | Price Comparison
| Item | Sweaty Betty | Lululemon |
|---|---|---|
| Leggings (hero style) | £85–£120 | £98–£128 |
| Sports Bra (medium impact) | £50–£75 | £58–£78 |
| Running Shorts | £55–£70 | £62–£78 |
| Lightweight Jacket | £95–£135 | £98–£148 |
| Yoga Mat | £65–£85 | £68–£118 |
Price parity is close. Lululemon sits marginally higher on average — roughly £5–£15 more per item at equivalent quality tiers. Neither brand offers meaningful discounts outside of sale periods.
4 | Sustainability
Sweaty Betty
Uses ECONYL recycled nylon across multiple collections — made from ocean plastic and discarded fishing nets. Has a published commitment to increasing sustainable material use. ECONYL content is independently verifiable, not a brand claim.
Lululemon
Has a "Be Planet" sustainability programme with targets around material sourcing and end-of-life. Slower adoption of recycled materials but actively developing circularity programmes. Faced criticism for greenwashing claims in 2023.
On sustainability, Sweaty Betty has a clearer, more verifiable track record with ECONYL content. Lululemon has broader ambitions but has faced more scrutiny over the substance of their claims. Neither brand is without criticism, but Sweaty Betty's recycled material use is easier to quantify.
5 | Size Range
Sweaty Betty
XS to XXL across most core lines. Size range has expanded significantly in recent years. Extended sizes available on leggings, sports bras, and tops. UK sizing used.
Lululemon
Size 0–20 (US) in most lines — equivalent to UK 4–20. Extended sizes to size 24 in some styles. Generally considered slightly wider in extended size offering but varies by product line.
Lululemon has historically offered a marginally broader extended size range, though Sweaty Betty has closed the gap in recent collections. Both brands now cover the majority of body types in their core legging and top ranges.
6 | Style Differences
Sweaty Betty Aesthetic
British-influenced colour palette — more restrained, tonal, and trend-aware. Prints are bolder than Lululemon's but executed with a fashion edge. Strong gym-to-street crossover. Suit a slightly younger, fashion-forward customer.
Lululemon Aesthetic
Cleaner, more minimal silhouettes. Neutral-heavy colour palette with occasional technical-looking accents. Less trend-driven, more classic. Strong second-hand market because pieces stay relevant season to season.
Prints & Colours
Sweaty Betty releases seasonal prints that feel current. Lululemon sticks closer to solids and subtle patterns — lower risk, lower fashion impact. If you want activewear that looks like it came from a fashion brand, Sweaty Betty wins. If you want pieces that don't date, Lululemon has the edge.
Occasion Crossover
Both brands have moved into the lifestyle and travel category. Sweaty Betty's approach is more overtly stylish; Lululemon's ABC trousers and casual wear is more discreet. Lululemon has a stronger non-workout casual range overall.

8 | Frequently Asked Questions
Is Sweaty Betty as good as Lululemon?
In terms of core fabric quality and performance, yes — both are genuinely premium activewear brands with real technology behind them. The differences are in feel (Lululemon's Luon is softer and more cotton-like; Sweaty Betty's PowerSoft is sleeker), aesthetics (Sweaty Betty is more fashion-forward, Lululemon more classic), and sustainability track record (Sweaty Betty's ECONYL use is more verifiable). Neither brand has a clear quality advantage over the other.
Why is Sweaty Betty cheaper than Lululemon?
Sweaty Betty is not consistently cheaper — both brands sit in a very similar price bracket. Lululemon sits approximately £5–£15 higher on average per equivalent item. The price difference reflects Lululemon's larger global distribution and stronger brand premium in international markets, not a quality difference.
Which is better for running — Sweaty Betty or Lululemon?
Both brands have strong running-specific lines. Sweaty Betty's Zero Gravity legging is designed specifically for running with a lighter weight and faster wicking than their yoga-focused Power Legging. Lululemon's Swift Speed is their running-specific option. Both perform well — the choice comes down to the fit feel you prefer. Sweaty Betty's Zero Gravity feels slightly more performance-focused; Lululemon's running gear has a more lifestyle-crossover feel.

No. OD's Designer Clothing does not stock Lululemon. We are an authorised UK stockist of Sweaty Betty. We've written this comparison to help you make an informed choice, not to mislead you into thinking Lululemon isn't available anywhere — it is, through Lululemon's own stores and website.
Which brand is more sustainable?
Sweaty Betty has a clearer, more verifiable sustainability track record with their use of ECONYL recycled nylon — made from ocean plastic and fishing nets — across multiple product lines.

If verified recycled material content is important to you, Sweaty Betty currently has the stronger case.
